在儿科领域内引起 DIC 最常见的原因就是感染。小儿肺炎属感染性疾病,其病原体主要为细菌,其次为病毒。诱发 DIC 的机理如下:①损伤血管内皮细胞,暴露胶元组织,激活血液凝血系统。这是主要的。②血管内皮细胞损害,可释放组织凝血活酶,激活组织凝血系统。③能使血小板凝集、破坏,释放促凝血物质—血小板素3,加速凝 The most common cause of DIC in pediatrics is infection. Pediatric pneumonia is an infectious disease, the main pathogen of bacteria, followed by the virus. Induced DIC mechanism is as follows: ① damage vascular endothelial cells, gel tissue exposed, activate the blood clotting system. This is the main one. ② vascular endothelial cell damage, release of tissue thromboplastin, activation of tissue coagulation system. ③ can platelet aggregation, destruction, release of procoagulant substances - thrombocytochemistry 3, accelerate coagulation
